Blurred vision at night may be caused by visual fatigue, glaucoma and night blindness.
1. Visual fatigue: If there is no problem with vision in general, and this happens only occasionally, it is likely to be due to excessive use of eyes during the day, for example, watching electronic products for too long during the day, which may lead to visual fatigue, and insufficient eye adjustment at night, resulting in blurred vision.
2. Glaucoma: It often leads to atrophy of the optic nerve, resulting in blurred vision, especially at night.
3. Night blindness: it is a congenital hereditary disease, usually during the daytime, the symptoms are not obvious, but at night there will be blurring of vision, and with the aggravation of the disease, vision will gradually decline.
Blurred vision at night should pay attention to rest, if the symptoms are not relieved, need to consult a doctor in time.
